About this file
The document is a Horizontal Alignment Review Report for the Umpqua ERFO Repairs 2022 project (Site 3220-1.42), created by the Federal Highway Administration's Western Federal Lands Highway Division. The report provides detailed technical specifications for a road alignment, including precise geospatial coordinates, station points, and geometric characteristics of the road's horizontal design.
The alignment consists of multiple linear and circular elements with specific technical parameters, such as tangential directions, radii, curve deltas, and chord measurements. The alignment spans from station 300+00.00 to 303+65.60, with coordinate points tracked using northing and easting values. The design includes two circular curve segments with a 300-foot radius and varying delta angles (40.552° right and 15.818° left), and three linear segments with different tangential directions and lengths ranging from 18.046 to 32.161 feet.
